I'm trying to sync a Samsung S10e (Android 11) for the first time. The issues here are mostly on Samsung/Android's end, not MusicBee, but I have more hope of finding a solution or workaround on the MB end.
It took me a while to get the wired sync working right; I thought for a minute my SD card might be going bad but it's doing ok now. The problem was mainly that when the phone locked, MB couldn't write to it anymore, but even once I got it unlocked I seemed to have a lot of errors until I completely restarted MusicBee and the sync. I can't disable the lock without removing my fingerprints, etc, so as a workaround I'm playing music in GMMP with the "Keep Screen On" setting enabled. (But the playback skips while MB is trying to write to the SD card so I have the volume all the way down... whatever.)
Meanwhile, I've set up the wifi sync app, hoping that the new phone won't have whatever issue wsa preventing it from seeing MusicBee on my old phone. Looks good until I go to preview. Then this happens:
Basically, when the app asks me to select a folder, Android won't let me select the root SD folder. If I select the MusicBee folder, MusicBee refuses it because it's not the root SD folder. Any chance that could be updated on the MB end? I would love to be able to select the MusicBee folder as my root sync folder in the first place.
Update: I think part of the issue with the wired sync might have been physical after all, not the SD card but the cable. It was definitely disconnecting even without the phone locking. Finally did get everything transferred with no errors.
